The fuel gauge in the 300D gets a little wonky around 1/2 a tank. I know eventually it needs a new sending unit, but until I can afford one (other priorities.....wife's car needs tires, youngest kids needs braces, the list goes on and on.....)

Anyway, for now I'm filling up the tank and then using the trip odometer to figure out my range. Like I said, the gauge seems fairly accurate to just above a half tank, then starts sticking and jumping.

Ok the question. What is a good estimate (in miles...) of the range of a half tank of fuel? I could probably figure it out easily enough myself, but I thought I would ask. I drive 95% of my time on open two lane roads at speeds of 55-70. Based on that, I figure about 225-250 miles puts me in the half tank area?

What do you all say?

Thanks in advance,

Glenn
